What Is Insomnia — and What Can You Do About It?

Insomnia is one of the most common sleep complaints seen in clinical practice. Yet for many people in South Africa, it goes unaddressed for months or years — not because nothing can be done, but because it can be hard to know where to start.

This page is Slumbr's guide to understanding insomnia: what it is, how it shows up in real life, what the evidence says about treatment, and how an online physician-led clinic can help you take the next step.

Key takeaways

Insomnia means difficulty falling asleep, staying asleep, or waking too early — happening often enough and long enough to affect how you function during the day.
Clinicians use a simple framework to distinguish a brief episode from chronic insomnia: three or more nights per week, for three or more months, with meaningful daytime impact.
Insomnia is not one pattern — it shows up differently for different people, and identifying your pattern matters for how it is approached.
Cognitive behavioural therapy for insomnia (CBT-I) is the evidence-based first-line treatment for chronic insomnia, recommended by international sleep medicine bodies ahead of medication.
Prescription medicine is only considered after a consultation with a physician, where clinically appropriate — it is never a substitute for understanding the underlying pattern.
Slumbr's free Sleep Pattern Assessment is a good first step. It is not a diagnosis, but it helps identify your pattern and what the right next step might be.

What does insomnia actually mean?

Insomnia is not simply "not sleeping well." Clinically, it refers to persistent difficulty with sleep onset, sleep maintenance, or early-morning awakening — combined with adequate opportunity for sleep — that causes meaningful difficulty during the day.

That last part matters: daytime impact. Insomnia is defined by more than what happens at night. The fatigue, concentration problems, irritability, or difficulty performing at work or home are part of the picture.

What about a bad week of sleep?

A short stretch of poor sleep — before a big event, during a stressful period, after a loss — is very common and usually resolves on its own. Clinicians often refer to this as acute or short-term insomnia.

The threshold that distinguishes a brief episode from what is called chronic insomnia is sometimes described as the "3-3-3 framework":

Three or more nights per week of difficulty sleeping
For three or more months
With meaningful daytime impact

This framework maps directly to the diagnostic criteria set out in both DSM-5 and the International Classification of Sleep Disorders (ICSD-3). It is not a rigid diagnostic formula — clinical assessment considers the full picture — but it is a useful way to understand when a sleep problem has moved beyond a temporary disruption.

How does insomnia show up?

People often assume insomnia just means lying awake at bedtime. In practice, it presents in several distinct patterns:

Difficulty falling asleep (sleep-onset insomnia) Lying awake for a long time after getting into bed, mind racing or body unable to settle.

Waking through the night (sleep-maintenance insomnia) Falling asleep reasonably well but waking repeatedly — sometimes for short periods, sometimes for hours — before the alarm.

Waking too early Falling asleep and staying asleep for the first part of the night, but waking significantly earlier than intended and being unable to return to sleep.

"Tired but wired" Feeling exhausted during the day but becoming alert and restless at night — the opposite of what you need. This pattern often involves a disrupted relationship between the body's arousal system and its sleep drive.

Sleeping at the wrong time Difficulty sleeping at conventional hours but sleeping well at other times — sometimes a sign of a circadian rhythm component rather than insomnia alone.

These are not mutually exclusive, and many people experience more than one. We cover each pattern in more depth in our Journal.

Why does the pattern matter?

The pattern shapes the approach. A physician assessing insomnia wants to understand not just whether you sleep badly, but how you sleep badly, what your sleep history looks like, what else might be contributing, and what has and has not worked before. This is why a structured assessment — rather than a generic "sleep tips" article — is a meaningful first step.

Slumbr's free Sleep Pattern Assessment is designed to do exactly this. It takes around ten minutes, gives you a clearer picture of what is happening, and helps identify what the appropriate next step might be. It is not a diagnosis — but it is a clinically informed starting point.

What does the evidence say about treating insomnia?

CBT-I is first-line for everyone

The most important thing to know is this: the first-line treatment for chronic insomnia is not medication. It is cognitive behavioural therapy for insomnia — CBT-I.

CBT-I is a structured, evidence-based programme that addresses the thoughts, behaviours, and habits that perpetuate insomnia. It works by identifying and changing the patterns that keep insomnia going — things like irregular sleep schedules, time spent awake in bed, and the hyperarousal cycle that makes sleep feel effortful.

The American Academy of Sleep Medicine (AASM, 2021) and the European Sleep Research Society (ESRS, 2023) both recommend CBT-I as the first-line treatment for chronic insomnia in adults, ahead of medication. This is not a new or emerging finding — it reflects decades of clinical research.

CBT-I is effective for the full range of insomnia patterns described above, regardless of how long someone has had the problem.

What about medication?

Prescription medicines that support sleep exist, and for some people they play a role. But medication is only one part of the picture — and it is never the starting point.

At Slumbr, prescription medicine is only considered after a consultation with a physician, where clinically appropriate. It is not directly purchasable, and it is not a substitute for understanding what is driving the insomnia. A physician-led approach means that any recommendation — whether it involves CBT-I, lifestyle changes, or, in some cases, medication — is based on your specific clinical picture, not a generic protocol.

What is the role of an online physician-led clinic?

Many people in South Africa do not have easy access to a specialist sleep clinic or a GP with dedicated expertise in sleep medicine. Online care changes this — but not all online sleep services are the same.

Slumbr is a physician-led insomnia clinic. This means your care is overseen by a doctor, not a wellness app or an automated tool. Assessments are clinically structured. Consultations involve a qualified physician. Recommendations — including any discussion of prescription medicine — reflect clinical judgement, not a one-size-fits-all approach.

This matters because insomnia can be straightforward, or it can be layered with other factors — anxiety, pain, other sleep disorders, medication effects, shift work, life circumstances. A physician can recognise the difference.

Who is Slumbr for?

Slumbr provides online sleep support for adults aged 18 and over across South Africa. Our consultations are conducted remotely, making it possible to access physician-led care without travelling to a specialist.

Slumbr does not provide emergency care. If you are in crisis or have thoughts of self-harm, please contact SADAG on 0800 567 567 (24 hours, 7 days a week) or go to your nearest emergency unit.

When should you seek help for insomnia?

There is no strict rule, but a few signs suggest it is worth taking the next step:

You have had difficulty sleeping on most nights for more than a few weeks
Poor sleep is affecting your energy, mood, concentration, or ability to function
You have tried common sleep advice (consistent bedtime, reducing caffeine, avoiding screens) without lasting improvement
You are relying on alcohol or over-the-counter products to help you sleep
You are concerned that something else — anxiety, pain, another health condition — may be connected to your sleep

If any of these apply, the right next step is not another sleep tips article. It is a structured look at your specific pattern.

Sleep patterns we cover in more depth in our Journal

Slumbr's Journal covers each of the insomnia patterns described above in dedicated articles: sleep-onset insomnia, sleep-maintenance insomnia, early-morning waking, the "tired but wired" state, and circadian-related sleep difficulties. We also cover what to know about sleeping tablets in South Africa, the role of sleep hygiene and its limits, and what to expect from CBT-I. And if you are unsure whether it is time to get help, see when to see a doctor for insomnia.

Frequently asked questions

Is insomnia a mental health condition?

Insomnia is a clinical sleep disorder, but it often occurs alongside anxiety, depression, or stress — and the relationship runs in both directions. Poor sleep can worsen mood and mental health; mental health difficulties can disrupt sleep. A physician assessment considers both, which is one reason a clinical approach is more useful than generic advice.

Can insomnia go away on its own?

Short-term insomnia often does resolve, particularly when it is linked to a specific stressor. Chronic insomnia — present for three months or more on most nights, with daytime impact — is less likely to resolve without some form of structured support. CBT-I has a strong evidence base for lasting improvement even in long-standing cases.

Do I need to take medication for insomnia?

No. CBT-I is the recommended first-line treatment and does not involve medication. Prescription medicine may be discussed during a consultation if a physician considers it clinically appropriate — but it is not the default, and it is not available without a consultation.

How do I know if what I have is insomnia or something else?

There are other sleep disorders — sleep apnoea, restless legs syndrome, circadian rhythm disorders — that can cause symptoms similar to insomnia, or that can occur alongside it. A physician assessment is the right way to work out what is going on. Slumbr's free Sleep Pattern Assessment is a good place to start: it is not a diagnosis, but it helps clarify the picture and whether a consultation is the right next step.

Start with a clearer picture of your sleep

The best first step is not a supplement or a sleep app. It is understanding your own pattern — what is happening, how long it has been happening, and what is likely driving it.

Slumbr's free Sleep Pattern Assessment takes around ten minutes. It is designed by physicians, structured to identify your specific pattern, and gives you a clear picture of what the appropriate next step might be. It is not a diagnosis, but it is a clinically informed starting point — available from wherever you are in South Africa.
